The electrons emitted from a nucleus during beta decay range from a minimum ener

Question

The electrons emitted from a nucleus during beta decay range from a minimum energy of zero up to a maximum of Emax. However, the energy of the nucleus is always reduced by Emax. What explains this difference in energy?

a. Nothing needs to be explained; momentum and energy are not conserved in beta decay.

b. A neutrino of energy Emax - Eelectron is emitted from the nucleus along with the electron.

c. A positron is also emitted by the nucleus but quickly annihilated.

d. A photon of energy Emax - Eelectron is emitted from the nucleus along with the electron.

e. Only momentum has to be conserved in beta decay, not energy.

Would appreciate any help!! Will rate w/in 24 hrs based on correctness and explanation!

Explanation / Answer

d. A photon of energy Emax - Eelectron is emitted from the nucleus along with the electron.
